LASTINGHMACHIN.

SPECIFICATION forming part of Letters Patent Ta-378,446, dated February 28, 1888.

Application iled May 31, 1887. Serial No. 239,749.

To @ZZ w/'Lom/ t may concern:

Be it known that I, W. HATCH, of Rochester, county of Monroe, and State of N ew -York, have invented an Improvement in Lastingdllachines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object toimprove that class of lasting-machines wherein the upper is laid over upon the inner sole by means of jaws, the last and upper thereon being mounted upon a jack.

vlin this invention I employ jaws composed of two plates, but with them I have combined crimpingslides, and at the same time I so modify the shape of the jaws and the time of their movement that the crimping-slides rst act upon the upper at the toe and heel of the last to lay the upper over upon the inner sole, and thereafter, in the forward movement ofthe crimping-slide, or after the crimping-slide has come substantially to rest or is coming to a position oi' rest, the jaws act to lay the sides ofthe upper over upon the inner sole at the rear of the toe and between the heel end of the inner sole aud the shank. The upper of the shoe to be lasted prepared, as will be described, by cement, or as described in my application, Serial No. 227,659, is placed over the lastholding spindle of a jack, and thereafter the last is applied to the top of the said spindle and the upper is drawn up above the level of the bottom oi' the last by means of pinchersin the hand of the operator engaging the toe of the upper. In this condition the upper is acted upon by a combined vamp and toe wiper which is raised against the vamp at or near the hall of the last, and while the said wiper is in contactV with the said vamp it is moved forward from the ball ol' the last to and about the toe, stretching the upper and iitting the vamp to the last, and then the inner soie properly cemented, as will be described, with cement, is laid upon the bottom of the last. The inner sole having been applied, the ce mented edges of the upper at and along the ball of the last at one side is grasped by pinchcrs and pulled up and over upon the inner solo, where it is held by the thumb of the operator, while the pinchers held in the other hand are taken from the upper and used (No model.)

as a hammer to strike the upper near its edge to set the same. This done, the same thing is repeated along the opposite edge of the last, and thereafter the crimping-slide and the toejaws are moved forward and made to act first upon the toe to lay it over upon the inner sole, and then upon the edges of the upper between the toe and ball 'of the last, the said slide and jaws being left in such position to hold the overturned edges of the upper closely down upon the inner sole. The operator now again takes the pinchers and draws up the upper about the shank oi the last, first at one and then at the other side of the last, and then the heel or quarter part of the vamp and the stiffener within it is acted upon by the heelcrimping slide and its accompanying heeljaws, as will be described. The block on which the heel-lasting jaws slide is provided with a counter-holder to impinge against the quarter and hold it and the stiii'ener within it up snugly against the last, while the jaws act to lay the quarter and stiffener over upon the inner sole. The counter-holder is jointed so as to permit it to rise and fall somewhat with the shoe as the latter is moved vertically below the jaws when pressure is being applied to the spindle of the jack.

The particular mechanical features in which my invention consists, as well as the method invented by me, will be hereinafter especially pointed out in the claims at the end of this specification.

Figure lis a vertical section of a lasting machine embodying this invention; Fig. 2, a top or plan view of Fig. l, the jaws being partially broken out to show the crimpingslides under them; Fig. 8, a right-hand end View ofthe upper part of thejack illustrated in Fig. 1,chiefly toshow the toewiper; Fig. 4, a righthand side elevation of Fig. 3; Fig.l 5, a partial section of Fig. l in the line w fr, looking to the right; Fig. G, a detail, to be referred to, of the rotating table and bed and locking devices. Fig. 7 is a detail showing the toe-jaw and crimping-slide under it as they appear when the jaw is spread open and the jaw and slide are ready to be started forward to act upon the toe of the upper pulled above the bottom of the last, and Fig.8 shows separately one of the studs on which the jaws turn.

The standard A and its arm A constitute IOO the frame-work for the working parts. rllhe arm A has attached to it by a shouldered bolt, A, a bed, A3, having at suitable intervals notches A4, (see Figs. and 6,) which are engaged by a lever, as a or b, pivoted" upon aV table, B,whencver it is desired to lock the Said table iirmly in position with its toe or heel crimping jaws opposite the jack to be described, the table, as herein shown, being adapted to be rotated upon or about the bolt A2 as a center. The bed referred to has three notches, either of which may be entered by that one of the levers, c or Z1, next the jack. The levers are made to enter av middle notch when a'straight last is being used, and one or the other of the outside notches, according to whether a right or left boot or shoe is being lasted.

For lasting the toe I employ a toe-crimping slide, cx, and. above it a pair of jaws, c c', all carried by a stud, c2, erected upon a sliding plate, c, free to slide in a block, c4, pivoted at c5 on a carriage, c", having a foot which may be made movable in a guideway or slot of the table B by means of a screw, el, one end of which (see Fig. l) enters a lug, 0B, of the table, the screw having an annular groove which is entered by a screw, c, leaving the screw c7 free to be rotated to thus adjust the carriage c6.

The block cthas screwed into it a screw, cw, provided near its head with a shank having a shaped annular groove, (see Fig. 1,) which is seated in the forked upper end of an caiga, of the carriage c, the material of the ear entering the said groove, permitting the screw to be rotated, yet not to be moved longitudinally; but the screw is free to be moved up and down in the forked upper end of the said ear, and it does so move .whenever the screw cw is rotated to adjust the block c4 with relation to the carriage c,which is frequently necessary in order` to adapt the jaws to the longitudinal curvature or spring of the bottom of the last, especially at the toe and heel thereof. The block c4 has erected on it a stud, c3,\vhicl 1 enters slots (see Fig. 2) in the tails of the plates c c', as usual, the said stud also first passing through a longitudinal slot of the toe-crimping plate 0X.

The slide-block c3, of dovetail shape, (see Fig. 5,) is provided at one side above the block c* with teeth c, to be engaged by the teeth of an intermediate gear, c, engaged by a pinion, c1, secured to or actuated by a lever, as c, movement ofthe said lever by the hand of the operator enabling both the crimpingslides andjaws to be moved forward, a pawl-con trolling lever, c, pivoted at 02 on the said lever d", normally acting to cause one end of a pawl, c, to remain in engagement with a stationary ratchet-toothed4 plate, c, to thus hold the hand-lever, and consequently the jaws and slide,in any position in which they may be left by the operator when he takes his hand from the said lever.

The shoulders of the studs c2 and cl2, where l they support the crimping-slide and jaws above them, are rounded, beveledyor ,shaped substantially as shown in Figs. 5 and 8, to thus enable the said slide and also the jaw above it to rock more or less in order that the said slide and jaw may accommodate themselves to slight differences in the height of the outer or inner side of the last and to slight inequalities in thickness of the stock.

For lasting the heel I employ a heelcrimping slide, dx, and a pair of jaws composed of slotted plates d d, all mounted on a common stud, d2, of a slide-plate, d3, which enters a groove in the block d4, pivoted at d5 on a carriage, d, made adjustable longitudinally on the table B by a screw, dl. The slide-block d3 is toothed at d, as described of the slide plate c3, and is moved horizontally when it is desired to close and open the jaws by an in-A termediate, gear d15 gear, di, and hand-lever d1?. The guide-block d4, pivoted at d5, is made adjustable about the said pivot by a screw, d10, constructed, as described, of the screw om. The slide-block d3 is provided at its outer end with a counter holder or presser composed chiefly of a head, E, pivoted upon or jointed to a sliding shank, cx, surrounded by a spring, c, which normally acts to force the holder outward. The last f is held on a heel-pin, f', pivoted at fX on stands f2, erected upon a head, f2, free to rotate on a stud-screw, f 3, at the top of a spindle, f4, entering a collar, f5, in the upright A, all forming a jack.

The spindle f4 is sustained by a spiral spring, f, resting on an adjusting-nut, f6, which may be rotated onk a threaded part of the guide-rod f l, attached to a stand, f s, of the upright A, the said guide-rod entering loosely a hole, f, in the spindlef, the said spring normally acting to lift the jack, the strength of the spring being adjusted by turning the nut f 6.

The jack may be lowered by a link, g, and treadle g whenever desired, which is done when the shoe with the upper upon itis placed next the guide-blocks c* or dt, preparatory to causing the crimping slides and jaws to lay the upper over upon the inner sole, the foot being removed from the treadle as soon as the crimping-slide is moved far enough forward to catch the upper over the inner sole, the removal of the foot from the treadle enabling the spring f15 to act and yexert an upward pressure on the last to measure the pressure of the slideand jaws on the upper, the stronger the spring the greater the friction between the slide and jaws andthe upper, and vice versa. The spindle is depressed when it is desired to withdraw the slide and jaws and remove the shoe or change its position to enable a heel to be lasted after a toe has been lasted. The head receives the foot fm of a carriage, f 90, made adjustable by ascrew, f. The carriage f90 has attached to ita lug,f13, on which is pivoted the arms f 1*, which hold the pivots for the combined vamp and toe wiper w, composed, as herein shown, of two pieces of metal, (see Figs. 3 and 4,) having suitably riveted or attached to them a piece of ICO IIO

vt-o the last and to the toe thereof.

The arms f have connected to them stron g springs f1, which normally act to keep the vamp and toe-wiper pressed backward toward or against the toe of the upper on the last, or against a stop or piu, as 22, in an ear, 23, a rod,f1l, and springfs, (see Fig. 3,) enabling the said vamp and toe-wiper to be contracted or to be spread apart, according to the width ofthe last or of the shoe being lasted. The metallic frame of the toe-wiper has jointed thereto by a bolt, 3, two links or rods, 2st, pivoted toanear, 4, of a rocking sleeve, t, mounted in the head of the carriage fi, the sleeve turning on a stud, 5.

rEhe rocking sleeve t has attached to it a lever-handle if, the movement of which in the direction of the arrow in Fig. a, the arms f1* then resting against the stop 22, causes the rods 2i to lift the edge of the combined vamp and toe-wiper against the upper, and as the rods 2a continue to move they cause the said wi per, borne closely against the upper, to travel forward, drawing or pulling and fitting it about the last until the wiper arrives in the position Figs. 1,3,and 4, a pawl, 34, carried by the hand-lever if, engaging the stationary ratchet-toothed sector h and causing the com-A bined vamp and toe-wiper to remain in posi tion where left .by the operator, and hold the upper after its edge has been pulled up above the bottom ol the last by pinchers, and also while the upper is being acted upon by the devices employed to crimp or lay the edges of the upper over upon the inner sole about the toe and along the sides of the inner sole, as described.

The toe having been lasted, the jack is depressed by the treadle in orderthat the toecrimping slide or plate and the jaws may be retracted, the toe-wiper is lowered, the jack rotated half around to bring the heel of the lastin position to be lasted, and the table is rotated to bring the heel-lasting jaws in work ing position. rlhe lower end of the heel-pin f/ is tapped for the insertion of a screw, 35X, which, provided with a suitable neck and collar, 35, is inserted loosely in a hole in the ear or cross-plate 37X of the base f2, rotation of the screw 35X, itslongitudinal movement being restrained,resulting in tipping the heel-pi n, so as to place the heel and toe ends of the bottom ofthe last more or less out of true horizontal plane, according to the shape of the last, the class of upper being lasted, and the extent of the upper to be acted upon by the toe-wiper.

The sole-leather part 2 of the toe-wiper is set with its edge uppermost to wipe the vamp to the last and hold the whole toe of the upper in position on the last all around the same while the operator turns the upper overon the inner sole.

To avoid the use of tacks for lasting, they being very objectionable, especially in line or in the better class of shoes, I have devised a method of holding the upper to the inner sole by means of cement.

The cement used contains rubber, and is applied to not only the inner sole, but also to the edges of the vamp or its lining, and preferably the edges of the vamp and lining will bc stitched or cemented together. The cement so applied is permitted to stand long enough for the cement to become tacky, so that when the cemented surfaces are brought together they adhere readily and retain their hold.

l have herein described a method of lasting shoes; but the same is notherein made the subject of claim, except when the wiping of the vamp and toe, as described, is made one ofthe steps, for claim to other parts of the method is made in another application for United States patent tiled by me March 13, 1887, Serial No. 238,089, the said application also describingthe further steps of applying the outer sole.

The combined vamp and toe wiper herein shown and its actuating mechanism are not herein broadly claimed, for the same is made the subject of claim in another application, Serial No. 237,566. filed by myself and Joseph Pitcher, May 9, 1887.
